Text-mined interactions from Literome
Kanaya et al., Clin Cancer Res 2000
:
These findings suggest that
p53 repressed telomerase activity through down-regulation of hTERT transcription and that interaction of p53 with
Sp1 or other transcription factors may be
involved in this regulation
Lee et al., Oncogene 2000
(Carcinoma, Hepatocellular...) :
Wild-type
p53 inhibited binding of transcription factors
Sp1 and TBP on the P4 promoter, while p53mt249 enhanced the formation of transcriptional complexes through enhanced DNA-protein ( Sp1 or TBP ) and protein-protein ( Sp1 and TBP ) interactions ...
p53mt249 stimulates transcription factor
Sp1 phosphorylation which might be a cause of increased transcription factor binding on the P4 promoter while wild-type p53 does not
Xu et al., Oncogene 2000
(Breast Neoplasms...) :
Finally, wt
p53 inhibited
Sp1 binding to the hTERT proximal promoter by forming a p53-Sp1 complex
Amini et al., J Biol Chem 2004
:
Expression of
p53 further enhanced the level of Vpr-Sp1 mediated transcription activation of p21 through the sequence spanning -84 to -74 and
increased the DNA binding activity of
Sp1 in the presence of Vpr. Results from glutathione S-transferase pull-down assay showed the association of Vpr with p53 in extracts containing Sp1
Pietrzak et al., Biol Chem 2008
:
As shown by electrophoretic mobility shift assays,
Sp1 binding to the sites located in the -295 to +16 MCL-1 promoter fragment was decreased in the
presence of
p53
Bheda et al., Oncogene 2008
:
Wild-type
p53 suppressed
Sp1- and YY1 mediated induction of the EGFR promoter ... We conclude that acute loss of p53 in normal HKc induces EGFR expression by a mechanism that involves YY1 and
Sp1 and does not
require p53 binding to the EGFR promoter
Króliczak et al., Acta biochimica Polonica 2008
(Neoplasms) :
Sp1 and NFkappaB binding to the probes resembling their putative binding sites present in the S100A6 promoter was decreased in the
presence of wild type
p53
Lin et al., Cancer Res 2010
(Lung Neoplasms) :
Low level of exogenous
Sp1 enhanced the repressive activity of endogenous
p53 on the DNMT1 promoter whereas high level of Sp1 upregulated DNMT1 gene expression level in A549 ( p53 wild-type ) cells
Fuchs-Young et al., Breast Cancer Res Treat 2011
(Cell Transformation, Neoplastic...) :
Previous studies from our laboratory have shown that
p53 regulates ER expression transcriptionally, by binding the ER promoter and forming a complex with CARM1, CBP, c-Jun, RNA polymerase II and
Sp1
Hwang et al., Proc Natl Acad Sci U S A 2011
(Neoplasm Invasiveness) :
Wild-type
p53 negatively
regulates MET expression by two mechanisms : ( i ) transactivation of MET targeting miR-34, and ( ii ) inhibition of
SP1 binding to MET promoter
Dhar et al., Cancer Res 2011
(Carcinoma, Squamous Cell...) :
Exposure to DMBA and TPA activated p53 and decreased MnSOD expression via
p53 mediated suppression of
Sp1 binding to the MnSOD promoter in normal appearing skin and benign papillomas
Gu et al., J Cell Physiol 2012
(Breast Neoplasms) :
Oldenlandia diffusa extracts exert antiproliferative and apoptotic effects on human breast cancer cells through
ERa/Sp1 mediated
p53 activation
Chew et al., J Biol Chem 2012
:
Sulforaphane induction of p21 ( Cip1 ) cyclin dependent kinase inhibitor expression requires p53 and
Sp1 transcription factors and is
p53 dependent
Gualberto et al., J Biol Chem 1995
:
The presence of
Sp1 increased
p53 binding to its recognition sequence in the HIV-1 LTR, and experiments in Drosophila cells show that Sp1 is necessary for full transactivation by mutant p53
Bargonetti et al., Cell Mol Biol Incl Cyto Enzymol 1997
:
p53 represses
Sp1 DNA binding and HIV-LTR directed transcription
Ohlsson et al., Endocrinology 1998
(Osteosarcoma) :
p53 regulates insulin-like growth factor-I (IGF-I) receptor expression and IGF-I induced tyrosine phosphorylation in an osteosarcoma cell line : interaction between p53 and
Sp1
